Introducon
Thank you for choosing the UF1 to be a part of
your high performance music listening system.
Each UF1 is handcraed, using the very latest,
no compromise, cung edge technology and
componentry. This ensures the best possible
sound reproducon currently available and
guarantees many years of listening enjoyment.
We understand that you are eager to begin
listening; however, please take a few minutes to

concerning the operaon of your new amplier.
OAD Ultradelity equipment takes a considerable
me to run in before it performs at its best. The
duraon varies, but under some condions the
sound may connue to improve for over a month.
Beer and more consistent performance will be
achieved if the system is le switched on for long
periods. It is worth remembering however that
equipment le connected to the mains can be
damaged by lightning.
Aer reading this manual, if you have any further
quesons regarding your amplier, contact your
dealer or OAD Ultradelity customer service –
they will be happy to help you to make the most
of your new component.
Happy Listening!
Warnings
• To prevent re, or shock hazard, do not expose
your UF1 to rain or moisture.
• Do not place objects containing water on top
of this unit.
• This unit contains voltages which can cause
serious injury or death.
• Do not operate with covers removed.
• A power cord is shipped with your UF1 that
meets the required safety standards. It is
important for both safety and performance
that the standard cable supplied is not
modied.
• A switch at the front of the UF1 must be
accessible in case of emergency power
disconnect. For connued protecon against
re hazard, replace the fuse only with the
same type and rang (see page 3 for fuse
informaon).
• Your hi- system, including the UF1, can be
damaged by lightning and should be turned
o and disconnected from the mains when
there is risk of lightning strike.
• OAD recommends that all connecons to the
UF1 are made with either the mains power
cord disconnected or the front mains switch
le in the OFF posion.
• Refer servicing to your authorized OAD
Ultradelity dealer or service personnel.
Venlaon
Due to its highly powerful power supply the
UF1 will run warm to hot when in use. You must
allow for this in installaon, by providing for
free air circulaon around the product. Never
block any venlaon openings. Allow at least 60
mm of clearance around this product for proper
venlaon. Electronics should not be subjected to
sources of excessive radiant heat. Excessive heat
can shorten the life of the product.
Packaging
Save all packaging in a dry place away from
re hazard. Your CP1 is a precision electronic
instrument and should be properly boxed any me
shipment is made. It is very unlikely that you will
have to return your unit to the factory for service,
but if that should prove necessary, the original
packaging will protect your CP1 from unnecessary
damage or delay.
Interconnect Cables
RCA/XLR Interconnect plugs should be kept clean
and free from corrosion.
The UF1 is ed with silver plated oxygen free
copper RCA input sockets & Binding Posts that
will tarnish in me. Tarnished or oxidised silver
does not degrade the quality of contact. This is a
disncve property of silver plang. If you wish to
clean the connectors, switch o the equipment,
pull the plugs out of their sockets, and push them
back in again. Contact cleaners and “enhancers”
should not be used as the lm they deposit may
leave a deposit and degrade the sound.

1 AC MAINS INPUT
• The UF1 comes supplied with a detachable mains power cord. Connect corresponding end of the mains
power cord to the AC mains input of UF1 and the plug connected to a mains power source.
• Always disconnect the mains power plug from the mains power source rst, before disconnecng the
cable from the UF1’s AC mains input socket.
2 AUDIO IN
• The UF1 is ed with BALANCED and SINGLE-ENDED inputs.
• Single-ended inputs should be used with a preamplier (or electronic crossover, etc.) that has
single-ended outputs which do not invert overall phase or polarity. Disconnect any balanced cables.
• Balanced inputs can be used with a preamplier (or electronic crossover, etc.) that has balanced outputs.
Disconnect any single-ended cables.
3 SPEAKER OUTPUT
• The SPEAKER OUTPUT is the main output port that connects the UF1 to your loudspeakers. Use the best
available speaker wires. As your system improves in resoluon from the addion of quality components, it
becomes increasingly important to avoid the limitaons of inferior system interconnecons. It is important
sonically that your enre system be connected so that the audio signal arriving at the speakers has correct
absolute polarity or phase (i.e. is not inverted). Connect the black or (-) speaker terminal to the wire that
connects to the appropriate-channel (-) binding post on the amplier. Connect the red or (+) speaker
terminal to the wire that connects to the appropriate-channel (+) binding post on the UF1. Tighten the
binding posts rmly to ensure good contact for opmum sonic results.
4 FUSE HOLDER
• Your UF1 is already ed with a fuse. For protecon against re hazard, replace fuse with same type and
rang only. Installing an incorrect fuse may cause damage, thus voiding the warranty of your UF1.

In-built Protecon Funcons
In-built Protecon ensures safe operaon and a long lifeme. The UF1 Power Amplier has the following
protecon funcons:
Fuse
The mains connecon has a fuse which protects your UF1 against too high power consumpon. Please
replace with the same fuse type. The fuse is located within the mains switch on the rear side of the UF1.
Model 220 - 240 V, 50-60Hz 5A/250V an surge (T) M205
Model 100 - 120 V, 50-60Hz 7.5A/250V an surge (T) M205
Level Limitaon
If input signal levels become too high, then the so clip circuit will acvate. The acvated so clip circuit
may distort the output signal signicantly, thereby causing a reducon in sonic performance. Please ensure
that the input levels are within the limit of 2.6 Vrms for both single-ended and balanced connecons.
Over-Current
If the output current to the loudspeakers ever exceeds 15 amps, the speakers will electrically disconnect
from the UF1 automacally.
Over-Temperature
The temperature of the power transistors is permanently monitored. If the maximal operang temperature
is exceeded, despite the more than adequate cooling system, the power amp will automacally disconnect
from the speakers.
